Process and Steps of CNC Milling-KANOU

The term "milling" refers to any machining operation involving rotating cutting tools to remove material from a workpiece in manufacturing. There are two types of milling operations: manual milling and automated milling (CNC). Manual milling involves the traditional method of shaping and manufacturing items using manual tools and hand-operated machinery. The expected results heavily depend on the operator's knowledge, skill level, and experience. This article will focus on CNC milling.


What is CNC milling?


CNC milling is a method of machining where machine tools are controlled by computer programs. In CNC milling, precise machining of a workpiece is achieved by using pre-written programs that control the movements of the machine tools through a computer.


Milling involves the use of rotating cutting tools to cut materials such as plastic, metal, or wood. In the CNC milling process, a computer controls the spindle speed, feed rate, tool sequence, and tool paths for each tool. This ranges from 3-axis, 4-axis, and 5-axis milling to multi-axis milling. In 3-axis milling, movement occurs along the X, Y, and Z axes. 5-axis milling machines move along linear X, Y, and Z directions while also moving along rotational A and B directions, enabling the production of more complex parts.


The advantages of CNC milling include high precision, efficiency, good repeatability, and the ability to machine complex parts. It is widely used in the manufacturing industry, especially in aerospace, automotive, electronics, and medical equipment sectors.

CNC Milling Process Steps:


Part and Process Design:


Before engaging in CNC milling, it is crucial to design the parts and establish the machining process. This involves determining cutting paths, cutting speeds, feed rates, and other parameters.


CNC Program Development:

Employing specialized CNC programming software, create CNC programs based on the designed parts and process requirements. These programs encompass tool paths, cutting parameters, and instructions for coordinate axis movements.


Milling Machine Setup:

Secure the workpiece on the CNC milling machine, ensuring accurate positioning relative to the tools. Adjust fixtures, tools, and the worktable to guarantee precision and stability during machining.


Part Production:

Initiate the CNC milling machine, execute the loaded CNC program, and allow the system to autonomously control tool movements on the workpiece surface along predetermined paths. Initial operations may employ larger tools for material removal and achieving an approximate shape. Subsequently, tool changes contribute to the production of more precise machined parts. Precision CNC milling is achieved in the final stages, ensuring exceptional surface roughness and tolerance levels.


What are the CNC milling methods?


CNC milling centers can precisely process a variety of complex features. These features include threads, chamfers, grooves, and more. However, creating these features requires various milling operations, such as face milling, slot milling, side milling, contour milling, slope milling, thread milling, helical milling, copy milling, plunge milling, contouring at a constant Z level, drilling, and others.

How to choose the best precision parts manufacturer?


Choosing an excellent precision component manufacturer requires consideration from multiple aspects. It is essential to evaluate whether the manufacturer has a rigorous quality management system, extensive industry experience, and specialized knowledge, as well as whether they employ advanced production equipment and technology. Understanding their technical capabilities, quality control processes, and supply chain management abilities is crucial, along with assessing cost transparency and sustainability. Checking customer references and case studies helps evaluate the manufacturer's communication skills, while also ensuring that their products comply with certifications and standards. By comprehensively considering these aspects, you can choose a suitable manufacturer and establish a long-term partnership.
